Is my Nikon D90 defective? LCD Picture zoom. Weird Spider Webbing thing.

You can see the weird effect on image




When I zoom in on the picture, its gone




The actual picture on the computer.

Is my Nikon D90 defective? Or is this normal??

Nothing is wrong. Patterns in clothing can do this. This is the reason for the low pass filter on cameras to help avoid these patterns showing up - Moire is what it's called. I don't suspect it will show up if you printed the image. To date, with my D7100 that got rid of the low pass filter, I have only had one picture where the pattern showed up when the image was printed.

"Newton's rings", often caused by two transparent surfaces, especially if moisturized, touching each other... Could be a result of a dropped camera, or the excessive pressure being applied to a LCD... Nothing to do with the low pass filter.

I, unlike @BackdoorHippie, do not find enjoyment in wasting my time trying to get the proverbial horse, or Dragan, to drink so I won't.

Matt323 your camera is fine. As I said earlier, I have seen it before.

Well, I am sure it doesn't have anything to do with the fools and horses (me, being here a horse, right?). I just offered an (possible) explication of this phenomenon to our colleague matt323.
Say, would you buy me a beer, if I ever come to Utah (I would not refuse it - I'm a beer-drinking horse)?

Back display is a low-res jpeg preview. The preview is a single, small jpeg file that must be resized from it's full view form for any display size other than 100% zoom, which is why the zoomed and computer images look the same. This resizing will result in loss of resolution and the possible introduction of noise.

As Moab Man stated, what you are seeing here is called Moire, and it's induced by certain detailed patters, often found in clothing, and can pop up when the image is resampled within the camera. Marketing departments seem to like Moire more than post people, leading them to promote the removal of Anti-Aliasing filters, which eliminate this pattern in the actual photograph while simultaneously softening the image slightly, on many cameras.

Seriously though, if you are curious, take the image on your computer and repetitively resize it to 25% the current size. At some point you may just introduce the pattern again on the computer as you lose resolution.

I also see this moire in the view finder and it moves.

Are you sure you haven't dropped your camera, lately, and/or used it in an extremely humid environment?

Here was a post from a while ago where someone ran into the moire issue.

I purchased the camera brand new off of Ebay. The camera came brand new with all the accessories and I double check that the camera was new by checking the shutter count when I snapped my first picture. Checked out to be new. Maybe they stored it in a humid place? The seller said that they purchased the camera back in 2008 when it first came out.

This sounds like the opposite from what bothers "matt323" - he sees the moire only on his camera's LCD (while the photo itself does not show moire). Strange problem, indeed. But if I would have to choose between the two, I'd rather live with the patterns being shown on LCD, only...

this is true moab. I only see the moire effect on the lcd.

That's why I was saying have one printed and see if it is really there or not. I have only ever had the moire show up in one actual picture. And that link I posted earlier was similar in that sometimes based on magnification it was there or not. Don't remember if he ever printed one to see if it was actually there.

When you say in the viewfinder, do you mean in "Live View" or in the actual viewfinder?

The actual view finder. When I get ready to take a picture and I focus the camera (autofocus), I see these lines (transparent) also some black lines.
